HYDRANT.

SPECIFICATION forming part of Letters Patent No. 341,403, dated May 4, 1886.

Application filed June 15, i885. Serial No. 168,729. (No mofleli) To @ZZ whom it may concern:

Beit known that we, Jol-IN BURNETT and GEORGE Ercnna'r, both of Cincinnati, Hamilton county, Ohio, have invented a new and useful Improvement in Hydrants, of which the following is a specification.

Our invention relates to a construction of hydrants whereby the parts which control the passage of water are. made capable of being secured in their effective posit-ions by means which are located wholly in sight and above ground, and whose disengagement enables the withdrawal of said parts at any moment, for any desired purpose-such as inspection, lubrieation, or repair.

Other featu res of our invention are described and specied in the sequel.

In the accompanying drawings, Figure l is an axial section of a hydrant embodying our invention, the parts being in the condition in which the water supply is closed and the waste` way open. Fig. 2 is a similar section, the parts being in the condition in which the watersupply is open and the wasteway closed. Fig. 3 is a perspective view of the head.

A portion is broken away from each section for compactness of representation.

The service'pipe from the main is made preferably as shown at A, with a rectangular col- Iar, B, having in its end an annular groove, b, to receive the tapered extremity c of the L- formed inlet or suction tube O, whose screwthreaded portion c takes a correspondingly screw-threaded cap, D, whose lip (Z engages behind the collar B, so as to inclose an annular space or interstiee, E, for reception of aluting of soft metal, which is compressed and prov tected bythe nut or cap D. Lugs c on the upturned portion of tube C rest in a step, F, which is interiorly screw-threaded to receive the correspondingly screw-th readed lower end of the shaft or shell G.

. The tube Oterminates above in an expanded head or chamber, H, the aperture h in whose top receives the lower member, I, of our duplex barrel I J, within which work the cuppackings or piston-heads K L of the combined water-way and plunger, which consists of a principle pipe, M, of any requisite length, screwing above into a T-coupling, N, into which is screwed the discharge-spout O, and

below into anipple or valve-stem, P, having side orifices, p, which serve alternately as outlets for the waste water and as inlets for the supply water, as shown in Figs. l and 2, respectively.

The lower member, I, of the duplex barrel I J has side orifices, i, which, in the depressed condition of the plunger, (shown in Fig. 2,) serve as the inlet-ports for the supply water. Ihe upper member, J, of said barrel has side orifices, j, which, in the elevated condition of the plunger, (shown in Fig. 1,)serve as.outlet ports or wasteways for the residue of water that remains above the duplex piston after closure of the hydrant.

Both members I and J of the duplex barrel are formed open and bell-mouthed below to facilitate the drawinginto them of the cupleathers. The lower cupleather or pistonhead, K, is` secured by a nut, Q, upon the screw pat the lower extremity of the plungernipple or valve-stem P. This cup-leather K coacts with the inturned shoulder or offset at top of the barrel member I, to limit the upstroke ofthe plunger in the act f closing, as shown in Fig. 1.

The upper cup-leather, Ii, of the duplex piston-head K L is secured upon the plunger tube M by being pinched between the nipple l? and a washer, R.

A leather or other suitable gasket, S, is interposed between the top of the suction-tube O and the shoulder t" of the lower barrel, I. A rim, fi, on the top of barrel Iconiines a gasket, S', on which rests the lower edge of the upper barrel, J.

Screwed upon the upper extremity of the shaft G is a neck, T, whose danget receives screw-bolts U,which fasten the head V. The attachment of said head is furthermore made the means of holding in place the distant members constituting the barrels I J and their abovedescribed adj uncts. This is accomplished by the insertion of a washer, W, which presses upon sleeve X, whose lower'extremity rests upon the upper barrel, J, which in turn holds the part-s below it, including the lower barrel, I, firmly seated upon the suctiontube C.

Y Vhen it is desired to withdraw the plunger and its attachments from the fixed portions of the hydrant, it ismerely necessary to remove IOC the two bolts U, after which the plunger and the barrels can be lifted bodily out, and can be returned to their places Without necessity of engaging screw-threaded inaccessible portions-such as are liable to become clogged with saud,or to be rendered useless by riding ofthe screwthreads or otherwise. A slot, 0, in head V receives and guides the spout O, said slot heilig concealed by a collar, o, on said spout.

Screwed into the top ofthe T-coupling Nis a screw-ste1n, Y, which occupies a hand-nut, Z, Whose flange is contai ned in grooves o/ in the head V. By this means the plunger is capable of being elevated or depressed by simply rotating` the nut Z to right or left, so as to open or close the hydrant.

l is a shiftable plinth, \vhich,being made to rest upon the brick or other pavement surrounding the hydrant, is secured in place by a nail or key, 2, being driven into a notch, 3.

For summer use, when it is no longer necessary to get rid of the residue. a common closable faucet may besubstituted for thespout O and the plunger be permanently depressed to the position shown in Fig. 2.

We are aware that it has been proposed to secure a plinth to the stems ot' pumps, hydrants,&c.,by means offusible material poured into an annular space or cavity between the adjacent faces of said plinth and stem; but this is not the equivalent of our invention.

In a hydrant, the combination, With suction-tube C H and the fastening devices U V XV X, of the duplex barrel I J, having the side orifices, i and j, the gaskets S S, and the piston-heads K L, as set forth.

a. The co1nbinatio1i,with the stem G, of the shiftablc plinth l, having the notch 3,and the key 2 driven in said notch, as set forth.

5. The co1nbination,with the pipe G H and the stein G, of the two-part barrel I J, having orifices ij, respectively, and the plunger M P, having the packing-s K L and the openings p, substantially as and for the purposes set forth.

In testimony of which invention We hereunto set our hands.
